“she was shot because she was advancing on an officer with a knife, making herself a threat to him and the other officers.”
In this case that is what happened. Many other times the suicidal person is only a threat to themselves but still get shot. And I’m not referring to suicide by cop.
In one case SWAT was called because a man was inside his home threatening suicide. he was alone but there were reports of firearms in the home.
SWAT did what SWAT does. 369 rounds later the guy was shot, a cop was shot, and a cop was dead.
The guy never had a gun, the cops shot each other.
That the cops screwed up that time doesn’t mean they screwed up this time.
